The island nation of Mauritius has little in the way of natural resources – historically, it’s depended on imported petroleum to generate electricity.

But increasingly, according to Phys.org, leadership on the island is preparing for an energy-scarce future.

They’re investing in solar, wind and hydropower, but also leveraging a key crop on the island: sugar cane, which is now generating enough biomass to provide an impressive 14 percent of the island’s power.

Mauritius, which is a small island a bit to the East of Madagascar, is generating the power by burning a material called “bagasse”, which is left over after sugarcane is processed.

Power producers are recapturing carbon dioxide from the power generation process and using it to “add the fizz to soft drinks”, according to Phys.org.

Researchers have already heralded bagasse as a promising manufacturing material, but Mauritius is now demonstrating that it can also be an economical power source as well – even if it’s ultimately a stopgap to other renewables.

Mauritius’ energy innovations could presage the future of many other areas in the world, as areas with once-cheap fossil fuel energy start to feel the crunch of dwindling global fossil fuel resources.
